Artikel XXVII

Any contracting party shall at any time be free to withhold or to withdraw in whole or in part any concession, provided for in the appropriate Schedule annexed to this Agreement, in respect of which such contracting party determines that it was initially negotiated with a government which has not become, or has ceased to be, a contracting party. A contracting party taking such action shall notify the CONTRACTING PARTIES and, upon request, consult with contracting parties which have a substantial interest in the product concerned.
